i have a file structure like this in my PHP 7.1
Model/Abstract.php
Model/NTLStm.php
Model/SoapCl.php
Controller.php
i Called Model/Abstract.php in Controller like this:
use Model/Abstract as modelAbstract;
$abstract = new modelAbstract();
i tried to include the Model/NTLStm.php & Model/SoapCl.php in Model/Abstract.php like this:
defined('DS') OR define('DS', DIRECTORY_SEPARATOR);
require_once dirname(__FILE__) . DS . 'SoapCl.php';
require_once dirname(__FILE__) . DS . 'NTLStm.php';
echo 'success';
but it seems it always terminate the process in require_once , i already tried to put try catch like this:
try{
defined('DS') OR define('DS', DIRECTORY_SEPARATOR);
require_once dirname(__FILE__) . DS . 'SoapCl.php';
require_once dirname(__FILE__) . DS . 'NTLStm.php';
} catch(\Exception $e){
echo $e->getMessage();
}
but it won't print anything
Try using parentheses with require_once... like this:
require_once (dirname(__FILE__) . DS . 'SoapCl.php');
require_once (dirname(__FILE__) . DS . 'NTLStm.php');

I am pretty new to PHP so this may be a dumb question but yeah. I'm trying to get information about a user on instagram with this library: https://github.com/postaddictme/instagram-php-scraper
I've added the library and also the Unirest library so that it should work?
I also have this code in my index.php file:
<?php
require_once dirname(__FILE__) . '/Unirest/Exception.php';
require_once dirname(__FILE__) . '/Unirest/Method.php';
require_once dirname(__FILE__) . '/Unirest/Response.php';
require_once dirname(__FILE__) . '/Unirest/Request.php';
require_once dirname(__FILE__) . '/Unirest/Request/Body.php';
require_once dirname(__FILE__) . '/InstagramScraper/Instagram.php';
require_once dirname(__FILE__) . '/InstagramScraper/Endpoints.php';
require_once dirname(__FILE__) . '/InstagramScraper/Model/Account.php';
require_once dirname(__FILE__) . '/InstagramScraper/Model/Comment.php';
require_once dirname(__FILE__) . '/InstagramScraper/Model/Location.php';
require_once dirname(__FILE__) . '/InstagramScraper/Model/Media.php';
require_once dirname(__FILE__) . '/InstagramScraper/Model/Tag.php';
require_once dirname(__FILE__) . '/InstagramScraper/Exception/InstagramException.php';
require_once dirname(__FILE__) . '/InstagramScraper/Exception/InstagramAuthException.php';
require_once dirname(__FILE__) . '/InstagramScraper/Exception/InstagramNotFoundException.php';
use InstagramScraper\Instagram;
$account = Instagram::getAccountById(272308256);
echo $account->username;
?>
But this code does not want to run :/. I keep getting this error:
Fatal error: Using $this when not in object context in
C:\xampp\htdocs\Instagramposts\InstagramScraper\Instagram.php on line 313
I mean if it's a finished library it should immediately work? Anybody's got a solution?
You need to create an instance of the class (object) first before using the method. The method makes use of the "this" operator which needs an object.
Your code should look like this:
use InstagramScraper\Instagram;
$insta = new Instagram;
$account = $insta->getAccountById(272308256);
echo $account->username;
I have a file that auto loads each of my classes.
This is what it contains:
spl_autoload_register(function($class){
require_once 'classes/' . $class . '.php';
});
require_once 'functions/sanitize.php';
require_once 'functions/hash.php';
But when I require_once this file from another php file that is inside my ajax folder, it will try looking for the classes, the function will look from my classes with the path: main_folder/ajax/classes instead of just main_folder/classes.
Does anyone know how to fix this?
FIX:
spl_autoload_register(function($class){
if (file_exists('classes/' . $class . '.php')) {
require_once 'classes/' . $class . '.php';
}
elseif (file_exists('../classes/' . $class . '.php')) {
require_once '../classes/' . $class . '.php';
}
elseif (file_exists('../../classes/' . $class . '.php')) {
require_once '../../classes/' . $class . '.php';
}
You should simple use this function just once - in the main file (usually index.php) and not in another files.
However if it's not possible (but I don't see any reason when could it be not possible) you can change it for example that way:
spl_autoload_register(function($class){
if (file_exists('classes/' . $class . '.php')) {
require_once 'classes/' . $class . '.php';
}
elseif (file_exists( $class . '.php')) {
require_once $class . '.php';
}
});
Here is a proper way, It should universally work.
EDIT: Make sure to specify levels on dirname in order to find the correct path.
spl_autoload_register(function ($classname) {
$file_realpath = dirname(realpath(__FILE__), levels: 1 /* Change that? */) . DIRECTORY_SEPARATOR . dirname($classname);
$classpath = sprintf('%s' . DIRECTORY_SEPARATOR . '%s.php', $file_realpath, basename($classname, '.{php,PHP}'));
if (file_exists($classpath)) {
echo "Loading <b>$classpath</b>...<br>";
require($classpath);
}
});
You need to know the absolute path to the classes directory, then just use a full qualified path to get there.
Make sure your document root is correctly configured with your http server. Furthermore this is usually solved by routing all requests to index.php and deriving the base path (document root) from there. Here is your code modified:
spl_autoload_register(function($class) {
$resolved = $_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'classes' . DIRECTORY_SEPARATOR . $class . '.php';
if(file_exists($resolved)) {
require_once $resolved;
} else {
// make it known to your that a class failed to load somehow
return;
}
})
Here is another implementation that I use for simple projects
This used to work in 1.5... I could set up the following code:
function startJoomla() {
define('_JEXEC', true);
define( 'DS', DIRECTORY_SEPARATOR );
$dir= dirname(__FILE__);
define('JPATH_BASE', $dir);
// load joomla libraries
require_once JPATH_BASE . DS . 'includes' . DS . 'defines.php';
require_once JPATH_LIBRARIES . DS . 'loader.php';
jimport('joomla.base.object');
jimport('joomla.factory');
jimport('joomla.filter.filterinput');
jimport('joomla.error.error');
jimport('joomla.event.dispatcher');
jimport('joomla.event.plugin');
jimport('joomla.plugin.helper');
jimport( 'joomla.utilities.utility' );
jimport('joomla.utilities.arrayhelper');
jimport('joomla.environment.uri');
jimport('joomla.environment.request');
jimport('joomla.user.user');
// JText cannot be loaded with jimport since it's not in a file called text.php but in methods
JLoader::register('JText', JPATH_BASE . DS . 'libraries' . DS . 'joomla' . DS . 'methods.php');
JLoader::register('JRoute', JPATH_BASE . DS . 'libraries' . DS . 'joomla' . DS . 'methods.php');
$mainframe = & JFactory::getApplication('site');
$GLOBALS['mainframe'] = & $mainframe;
return $mainframe;
}
$mainframe = startJoomla();
jimport('joomla.filesystem.folder');
jimport('joomla.filesystem.file');
And then, when I wanted to call something up from Joomla, I could do the following:
$custom = new CustomController(); // assuming there's a com_custom somewhere
This worked for 1.5. But in 2.5, the above doesn't work at all. I found a revised version of the load script:
function startJoomla() {
define('_JEXEC', 1);
define( 'DS', DIRECTORY_SEPARATOR );
$dir = dirname(__FILE__);
define('JPATH_BASE', $dir);
// load joomla libraries
require_once JPATH_BASE.'/includes/defines.php';
require_once JPATH_BASE.'/includes/framework.php';
require_once JPATH_BASE . DS . 'libraries' . DS . 'joomla' . DS . 'factory.php';
// Instantiate the application.
$app = JFactory::getApplication('site');
// Initialise the application.
return $app->initialise();
}
$mainframe = startJoomla();
This enables things like 'JFactory::getUser();' but will no longer allow me to utilize commands like 'new MycustomcomponentController();' Gives me 'core' Joomla functionality, but skips everything I installed. Is there an appropriate new revised compilation of jimport instructions or perhaps a different function of JComponent that allows me to call up my custom functions along with other components and models for use in external php files? Assume this will be run from a CRON or similar.
When I run test.php, why always error on !class_exists line?
This is test.php:
<?php //test.php
require_once './app/Mage.php';
Mage::app()->setCurrentStore(0);
Mage::setIsDeveloperMode(true);
require_once("test-class.php");
?>
This is test-class.php:
<?php //test-class.php
if (!class_exists("AClass")) {
class AClass {
public function AnAction() {
return 123;
}
}
}
?>
Because the Magento bootstrap app/Mage.php registers an autoloader, your call to class_exists() triggers attempts to load a class definition for this class. This behavior can be changed by passing false:
<?php //test-class.php
if (!class_exists("AClass",false)) {
class AClass {
public function AnAction() {
return 123;
}
}
}
?>
Further, the bootstrap sets up include path arguments for use by the autoloader:
$paths[] = BP . DS . 'app' . DS . 'code' . DS . 'local';
$paths[] = BP . DS . 'app' . DS . 'code' . DS . 'community';
$paths[] = BP . DS . 'app' . DS . 'code' . DS . 'core';
$paths[] = BP . DS . 'lib';
Placing your class definition in any of the above directories will allow it to be defined whenever a definition is required.
I'm just trying to build my first app on PHP Fog but there's a piece of code that doesn't run properly - works fine on localhost and other regular hosts though.
I use a modified version of TinyMVC, this is the code responsible for setting up autoloading:
/* Set include_path for spl_autoload */
set_include_path(get_include_path()
. PATH_SEPARATOR . FRAMEWORK_BASEDIR . 'core' . DS
. PATH_SEPARATOR . FRAMEWORK_BASEDIR . 'libraries' . DS
. PATH_SEPARATOR . FRAMEWORK_APPLICATION . DS . 'controllers' . DS
. PATH_SEPARATOR . FRAMEWORK_APPLICATION . DS . 'models' . DS
);
/* File extensions to include */
spl_autoload_extensions('.php,.inc');
/* Setup __autoload */
$spl_funcs = spl_autoload_functions();
if($spl_funcs === false)
spl_autoload_register();
elseif(!in_array('spl_autoload',$spl_funcs))
spl_autoload_register('spl_autoload');
Basically, it fails at the first class it should load, which is located in "FRAMEWORK_BASEDIR . 'core' . DS". The class filename is "framework_controller.php" and class name is "Framework_Controller" (tried lowercase as well). If I include the class manually it works but fails with autoload.
Here's the error message that I get:
Fatal error: spl_autoload(): Class Framework_Controller could not be loaded in /var/fog/apps/app7396/claudiu.phpfogapp.com/application/controllers/home.php on line 12
Any ideas as to what could the problem be?
I managed to sort it out:
function framework_autoload($className, $extList='.inc,.php') {
$autoload_paths = array (
FRAMEWORK_BASEDIR . 'core' . DS,
FRAMEWORK_BASEDIR . 'libraries' . DS,
FRAMEWORK_APPLICATION . DS . 'controllers' . DS,
FRAMEWORK_APPLICATION . DS . 'models' . DS
);
$ext = explode(',',$extList);
foreach($ext as $x) {
foreach ($autoload_paths as $v) {
$fname = $v . strtolower($className).$x;
if(#file_exists($fname)) {
require_once($fname);
return true;
}
}
}
return false;
}
spl_autoload_register('framework_autoload');
